Love my berk test pipe to death but I have a check engine light because of it. Just wondering what I could use to fill in some of the hole so my sensor won't get as much smog? Or if there is a better way?

thanks, ive seen this. But I was wondering if there is something I could fill my hole with. I figure if I make the berk hole a little smaller it should work just fine...
if not I guess I will just do this with only one fouler. how do you know what size to get?

 

nevermind, I fixed it. Used one non fouler

 

are u only supposed to use both or did one work for you cause i need todo the same thing

 

Well, if you have the berk test pipe like me I'm sure one will work. Look at the megan test pipe, it's not made to work without the foulers so there is no length to the passage to the o2sensor. Thats why you would need to use two. But with the Berk testpipe, most people don't even get a cel, it already has a long passage. But since some, like me, get a cel, we have to add the fouler. But I think one will work just fine.
Either way, they come in a pack of two so you could just use both.

Berk Test Pipe = 1
All others = 2

 

Also, the only hard thing about the whole process is drilling out the 1/2 hole. Seeing how I didn't have the right size drill bits it took me a while. But the install portion takes only a couple minutes..

 

i already have a hole drilled and the o2 censor screws right in but i get CEL, so if the o2 screws in will the anti foulers screw in perfect and by the way i have a custom str8 pipe

 

Uh, Im not sure I get exactly what you are asking. The foulers should be the same size as the o2sensor bolt. If you are using one and still get a CEL then just use two. You knly need to cut out one of the foulers..
